To all whom it may concern:

Be it known that I, ROBERT W.'IvEY, a citizen of the United States, residing at New London, in the county of Stanly and State of North Carolina, have invented a new and useful Window-Sash, of which the following is a specification.

It is the object of this invention to provide a metallic sash, so constructed that the same may expand and contract, without breaking the glass which is assembled with the sash. A further object of the invention is to provide a frame of novel and improved form, to provide novel means for assembling the constituent elements of the frame, to

provide novel means for holding the glassv within the frame, and to provide a mid rail of novel and improved form, cooperating with the sash proper to retain the glass therein.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood departing from the spirit of the invention.

In the drawings,Figure 1 shows the invention in perspective; Fig. 2 is a vertical section on the line AB of Fig. 1; Fig. 3 is a horizontal section on the line (3-1) of Fig. 1; Fig. 4 is a detail perspective of one of the angle members whereby the frameelements are terminally united; Fig. 5 is a detail perspective of one end of the mid rail of the sash; Fig. 6 is a detail perspective, showing one end of one of the socket elements which are assembled with the frame members; Fig. 7 is a side elevation of one of the supplemental strips which enter into the construction of the mid rail of the sash; and Fig. 8 is a top plan of the mid rail of the sash, one of the duplicated parts thereof being omitted.

In carrying out the invention, there is provided a frame, denoted generally b the numeral 1. This frame 1 consists of stiles 2, and cross rails 3,the stiles and the cross rails, in cross section, being of arched, or of U- shaped form. The meeting ends of the stiles 2 and of the cross rails 3 are mitered, as shown at 4. The stiles 2 and the cross-rails Specification of Itetters Patent. Ap ilieation'fl led Iebruary 7, 1811.

3 are held together by angle members 5, the arms of whlch are inserted into the ends of the stlles 2'and the cross rails 3, there being in the arms of the angle members 5, as Fig. 4 w ll clearly show, openings 6, adapted to receive screws 7 or other retainlng elements adapted to a like end, these retaining elements being engaged with the stiles 2 and with the cross rails 3. To the lower end of the sash, constructed as above described, a stop 8 is secured, by means of screws 9 or other securlng elements, the stop 8 being attached immediately to the lower cross rail 3, so as to abut with a similar stop upon the lower sash, as Fig. 2 will clearly show.

The invention further includes a plurality of arched socket elements 10, which are in- .serted into the open sides of the stiles 2 and of the cross rails 3, the socket elements 10 bemg back bent upon themselves, to form flanges 11, adapted to overlie the outer faces of the stiles 2 and of the cross rails 3.

The invention further includes a mid rail, denoted generally by the numeral 12. This mid rail, referring particularly to Fig. 8, consists of a body 14 and supplemental strips 21. The body 14 comprises a U shaped part 15, bent sharply u on itself, as shown at 16, to form flanges 1 protruding beyond the arched or U shaped part 15 of the body. These flanges 17 are back bent upon themselves, as shown at 18, the ends of the flanges being engaged, as shown at 19, with the U 1 shaped portion 15 of the'body '14.

The supplemental strips 21 which coop- 14 of the mid rail 12, consist of an arched body 22, bent upon itself as shown at 23, to form flanges 24. One of the supplemental strips 21 is shown in Fi 8. 'The bends 16 of the body 14 are engage in the bends 23 of one supplemental strlp, the arched body 22 of this supplemental strip, fitting within the arched portion 15 of the body 14. In the caseof the other su plemental strip, its bends 23 receive the bend: 18 of the body 14, the arched body 22 of the last named supplemental strip, fitting between the supplemental fianges20 of the body 14. The supplemental strips 21 are cut away, in their flanges 24, as denoted by the numeral 25, so that the ends 26 of the arched bodies 22 of the supplemental strips may be engaged within the socket elements 10, as will be understood readily.

The plates of glass which are denoted by the numeral 27, are received within the arched socket elements 10, and within the arched bodies 22 of the supplemental strips 21 of the mid rail 12. It will therefore e seen that since the socket elements 10 are free to slide within the stiles 2 and within the cross rails 3, and b reason of the further fact that the su p emental strips 21 of the mid rail 12 are ree to slide within the body 14 of the mid rail, any expansion and contraction of the frame, will be ineffective to crack the anes of lass 27. Alon their sides, and adjacent t eir upper en s, the stiles 2 'of the frame may be cut away, as denoted by the numeral 28, to receive the sash cord 29.

The window frame herein disclosed, is so constructed that it may be assembled and knocked down without difliculty, and furthermore, when the device-is in use, the panes of glass will be securely retained within the frame, without, however, being broken through thexexpansion and contraction of the frame. 4

Having thus described the invention, what is claimed is v 1. As an article of manufacture, a mid rail for a sash, consistin of an arched body having flanges extended beyond the body;

a supplemental strip fitting within the arched body and having flanges to inclose the bod and a similar supplemental strip fitting with in the flanges of the body, sai stri having flanges to mclose the flanges of-the ody.

2. In" a device of the class described, a frame comprising arched members having their open sides disposed toward the center of the frame; arched socket elements engaged in the open sides of the members; a

mid-rail consisting of an arched body having flanges extending beyond the body, a supplemental strip fitting within the arched body and having flanges to inclose the body, and a su plemental strip fitting within the flanges oi the body, said strip having flanges to inclose the flanges of the body; the flanges of the supplemental strips being cut away, adjacent the ends of the strips, and the en s of said strips being inserted into the socket elements.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two'witnesses.
